Building tests is surely one of the most difficult and time-consuming tasks for a developer, in addition to usually generating more lines of code than the added functionality. This is due to the various scenarios that need, or should, be verified.

Recently, I had to transfer my private keys to a different computer. Since this looks like a trivial task (it was my first time doing it), I have decided to search for a “how-to” blog post that details the steps required for this task.

A Content Delivery Network, can be described as a set of servers, distributed globally, with the purpose of providing content to users in an optimized way and in the shortest possible time.

Widely used in applications with high volume of simultaneous access, a load balancer is a computational resource used to perform load distribution between two or more servers of an application.

The main objective of building code tests in an application is to certify what was coded, that is, to guarantee that a given piece of code does what it should do.
